SPECIFICATION forming part of Letters Patent No. 579,975, dated April 6,1897.

Application filed .Tuly 3l, 1895.

To all whom, it' may concern:

Be it known that I, WEBSTER GILLETTE, a citizen of the United States,residing at New York, in the county and State of New York, have inventeda new and useful Improvement in Magneto-Electric Generators; and I dohereby declare that the following is a full, clear, and completedescription thereof, reference being had to the acoompanyin g drawings,making a part of the same.

This invention relates to an improvement in magneto-electric generators;and the invention consists in novel features and economy ofconstruction.

Figure l is a plan view of the instrument. Fig. 2 is front face view ofFig. l, showing the arrangement of driving-gear and their supports orframe. Fig. 3 is rear view of Fig. l, showing the form of the magnetsand connections. Fig. 4 is an end view of shaft L shown in Fig. l,showing its connections.

In Fig. l, A represents permanent magnets. Buis an armaturehavin gtrunnions C C. D is a cross-bar secured transversely to the permanentmagnets A by means of bolts E E, which supports the one end of thearmature B by trunnion C, passing through at or near its center. BarDhas attached to it a spring F, and insulated from it by block G ofnon-conducting material. H is an insulating-plug entering trunnion C towithin its bearing with bar D and ineasing a pin Lwhich is in turninsulated by means of an insulating-plug H. ll' is a plug insertedtransversely to and abutting against the insulating-plug H, which hasincased a pin l for the purpose hereinafter described.

In Fig. l a' a is a frame supporting a train of gear, a portion of whichis shown in sectional view. Frame a a is secured tothe permanent magnetsby the bolts E E. Attached to trunnion C/ of armature B is a pinion J.The trunnion C/ intersects the portion of the frame u.' about one-halfits thickness to act as a support and free to rotate between itssupports D and a. K is a toothed wheel that engages the pinion J andsupported by frames a' a. L is a shaft carrying a toothed wheel inbetween the supporting-frames a and a and in- Serial No. 557,682. (Nomodelz) tersects frame u, and about the center of a abuts againsttrunnion C', passing through a, thus giving two bearings, an'd extendsout from a" to permit the attachment of a crank or other device forrotating the same.

N is a section of inclosing case, which is preferably of insulatingmaterial. O is a sleeve of insulating material, such as fiber or rubber,which incases the shaft L and turns freely thereon. lncasing the sleeveO and iirmly attached thereto is a metallic cylinder l), having a collarP. The cylinder has an oblong square slot lt cut through its side, asalso has the insulating-casing O, that corresponds with the slot R,which admits a pin S, which is secured firmly to the shaft L. To oneside of the pin S is attached an insulating material S'. Secured to themetallic sleeve l) and incasing or surrounding the same is a spring T,one end of which is securely attached to the sleeve P. The other end ofthe spring T abuts against the insulating portion of the pin S.

U is a crank and handle securely attached to the sleeves P and G for thepurpose of rotating them on the shaft L. The slot R is so arranged thatin turning the crank U the insulating-sleeve O comes in contactwith thepin S. The sleeve l? is cut back, so as not to be in contact whileturning.

Y is a screw having a washer which intersects the shaft L for thepurpose of keeping crank and handle in position.

lV is a spring having a pin which passes through the case N and incontact with the flange P', which is connected with the spring F bymeans of the wire X.

To more clearly explain the action of the crank and handle, sleeves Oand P, flange li", Fig. 4L shows cross-section, in which L representsthe shaft, O the insulating sleeve, showing the oblong slot R, also thesleeve l with slot R in relative position to the slot in O and I), thepin S and SQ its insulating side as secured to the shaft and in relationto the sleeves F and O.

T is the spring attached to the sleeve l) at the point Z and free to actagainst the insulating portion of the pin S at the point Y.

It will be seen that by turning` the handle U the pin S is brought incontact with the sleeve O and will cause the shaft L to rotate, thusdriving the train et gear and causing the armature B to rotate Withinthe poles of the permanent magnets A, thereby setting up a current oi'electricity in the coil et the armature B, which is transmitted outthrough 3 or ft. lVhen the handle is released, the sleeves O and P areforced back by the spring T, bringing the pin S in contact with thesleeve l), thus making contact with the shaft L, and thus ont throughconnections 3 and ll, as shown in Fig. l, thereby shunting the circuitby the armature B. ln Fig. l, 3 may be the incoming connection and -rtthe outgoing connection, or vice versa.

By the foregoing description it will be seen that while turning thehandle U the circuit is established through the spring F, pin l, and pinl', through wire on the armature out at conductor 4r.

lVhen handle is at state of rest, the circuit is established fromconductor 3, through wire X, spring and pin lV to llange Fl, through l)to pin S, to shaft L, through. frame a a and gear, and out at contactet, thus shunting the armature out.

Fig. 2 is a face view to more clearly show the arrangement of the gear.

In Fig. 2 A is face view of the permanent magnet shown in Fig. l. o. ciis frame which supports the gear in which is the main dri ving-wheel,which matches into pinion l, which in turn revolves the gear-wheel l, asshown in Fig. l, which engages the pinion. J

and which is attached to trunnion C of ar mature lE.

`ln Fig. 2 Fis a collar attached to and forming a part of a sleeve P, asshown in l., which incases and is substantially secured to aninsulatingsleeve 0, as shown in Figs. 'l and 2.

U is a handle attached to sleeve l, as shown in Figs. l and 2, for thepurpose of revolving the train oi' gear as follows: iurnin g the handlerevolves the gear-wheel m, as previously shown in Fig. l, which matchesinto pinion lil, which revolves gear-wheel K, which matches into pinionJ, as shown in Fig. l, which is attached to the armature-trunnion Cl.The object is to increase the speed of the armature without occupyinggreater space.

Fig. 8 shows rear end view et Fig. l. jt is a permanent magnet. l is anarmature. l) is a frame with bolts F E and spring F. l) o represent endview ot the poles ot' armature l. e is insulated wire surroundingarmature B.

ln Fig. 3 it will be observed that the poles of the magnet A. arepresented lnll tace tothe poles ot the armature i3, thus transmittingthe full strength of magnetism to the armature while its poles arerotated between the poles of the permanent magnet A, while the pole l)rotates l'rom 3 to 5 and D from 0 to l. lt is seen that the fullmagnetic eltect is exercised. on the armature ll, as .its poles are indirect face with permanent magnet A. During its rotation from 3 to 5 and(l to at there is no current established within the wire surroumlingarmature Il. At the instant the poles ol armature l, leave the poles ofpermanent magnet rl a reverse polarity isset up in armature l, settingup a current of electricity l'or each change in opposite directionsthrough the coil of insulated wire surrounding armature ll,

It will be seen that by adding more magnets and elongating the armatureand bolts the capacity of the generator may be increased without otheralteration of parts.

llhat l claim as my iiivention, and desire to secure by Letters Patent,is-
